Fort de Barchon is a late 19th-century military fortress built between 1881 and 1884 as part of the Fortified Position of Liège in Belgium. Designed by General Henri Alexis Brialmont, it was one of twelve forts built around the city and stands out for being among the first military structures constructed entirely of unreinforced concrete rather than traditional masonry. The triangular fort played a significant role during World War I, being the first Liège fort to surrender during the German bombardment in August 1914. Today it serves as a museum open to public tours, typically held on the second Sunday of each month from April to November, offering visitors a glimpse into Belgian military heritage and 19th-century defensive architecture.
